I finally had a chance to build a terrarium so I did.

its a 65 gallon breeder tank. Its big.
I have a filtered pond side(about 30% of tank) and a the rest a 100% live plant land side.
I made the partition using 3/16" acrylic plexi glass.
1" of pea gravel
3/4" charcoal
canvas to keep the soil from mixing with the charcoal
100% fertilizer FREE potting soil/top soil mix. its a 50/50 mix.

ok so I tried to take step by step pics, but I got excited at times and forgot. SO - here are a few snap shots start to finish.
